Since it’s become the flavor of the month in the social media world, Pinterest and its ever increasing popularity has meant that it’s been covered extensively over the last few months with many wondering how long it’ll be until its growth will begin to waver. Despite the controversy surrounding it with regards to copyright, it keeps attracting new users and now, new research from Experian shows that this trend is very much here to stay as it’s now the third most popular social networking site in the U.S.

The report, entitled “The 2012 Digital Marketer: Benchmark and Trend Report“, found that Pinterest experienced a 50 per cent increase in traffic between January and February 2012, and received nearly 21.5 million total visits during the week ending January 28th 2012. That’s almost 30 times the number of total visits the site was receiving six months prior. Both this and the graph below shows highlights just how phenomenal Pinterest’s growth has been.
